The Naturehike SnowBird is built for the moments when the temperature drops below what most sleeping bags can handle. Rated for -10°C to -20°C and filled with 90% duck down at 650FP, this mummy-style bag delivers serious cold-weather performance in an ultralight package. The 20D nylon shell keeps weight to an absolute minimum while providing the durability needed for demanding winter conditions.
Available in three sizes — M (190 × 75 cm), L (205 × 80 cm), and XL (220 × 85 cm) — and multiple fill weights from 350g to 1090g, the SnowBird lets you dial in exactly the warmth-to-weight ratio your adventure demands. Whether you’re winter camping, alpine trekking, or pushing into sub-zero terrain, this is the bag that goes where others can’t.
